Fill a mixing glass two-thirds full with ice cubes.
Add the Scotch whisky, Drambuie, and dry vermouth.
Stir steadily for 20–30 seconds until well chilled and properly diluted.
Strain into a chilled cocktail glass.
Express a lemon peel over the surface to release its oils, then drape or discard as preferred.
Drambuie is itself Scotch-based, so the choice of base whisky matters - a blended Scotch keeps the drink harmonious, while a lightly peated single malt adds complexity without overwhelming the liqueur's honeyed character. Avoid heavily peated Islays, which can overpower the vermouth's delicate herbal notes.
